STRUCT EDAC_PRIV(9)

💖 struct edac_priv(9) 💖

okay so this is the kernel API manual, bestie — welcome to the OCM private instance data page ✨ no cap, that's the whole vibe of the NAME section, and we're gonna walk through it together, i promise it's not scary 🫶

✨ SYNOPSIS ✨

like, here's literally the whole struct, character for character, do not @ me:

struct edac_priv {
    void __iomem *baseaddr;
    char message[ZYNQMP_OCM_EDAC_MSG_SIZE];
    struct ecc_status stat;
    u32 ce_cnt;
    u32 ue_cnt;
  #ifdef CONFIG_EDAC_DEBUG;
    struct dentry *debugfs_dir;
    u8 ce_bitpos;
    u8 ue_bitpos[OCM_NUM_UE_BITPOS];
    u32 fault_injection_cnt;
  #endif;
 };

see that #ifdef CONFIG_EDAC_DEBUG; in the middle? yeah — those last four members only exist when that config's on, so keep that in mind, it's giving conditional realness 💅

🌸 Members 🌸

• baseaddr — the base address of the OCM, like the home address of the whole operation 🏠
• message — buffer for framing the event specific info, aka where the ✨lore✨ about what happened gets formatted
• stat — ECC status information, the main character of the status world 👑
• ce_cnt — Correctable Error count, keeping tally of the oopsies we can fix 🔧
• ue_cnt — Uncorrectable Error count, keeping tally of the oopsies we... cannot 😭
• debugfs_dir — directory entry for debugfs 🐛✨
• ce_bitpos — bit position for Correctable Error, very precise, very demure 🎀
• ue_bitpos — array to store UnCorrectable Error bit positions, and yes she's an array miss girl 💅
• fault_injection_cnt — Fault Injection Counter value, for when you're out here causing problems on purpose 🙈🔥
